摘要: Abstract Administration of 6-hydroxydopamine (6-OHDA) (i.c.) to rats produced a decrease in brain catecholamines (CA) and an increase footshock-induced fighting. Desmethylimipramine reduced this effect while lessening CA depletion. Blockade synthesis by either α-methylparatyrosine (AMPT) or FLA-63 did not produce any shock induced-fighting. d - l -amphetamine transiently decreased the 6-OHDA effect. -DOPA plus MK 486 effectively blocked it. Apomorphine reversed but was accompanied pronounced stereotyped behavior. The results suggest that depletion alone is sufficient facilitation shock-induced aggression. Degeneration adrenergic terminals also requisite for observed However, may be altered drugs which release CA, new or, act directly on receptor.
